The cryptodev API had specified that if the digest address field was
left empty on an authentication operation, then the PMD would assume
the digest was appended to the source or destination data.
This case was not handled at all by most PMDs and incorrectly handled
by the QAT PMD.
As no bugs were raised, it is assumed to be not needed, so this patch
removes it, rather than add handling for the case on all PMDs.
The digest can still be appended to the data, but its
address must now be provided in the op.

QAT PMD adjusts the buffer start address and offsets passed
to the device so that the DMAs in and out of the device are
64-byte aligned.
This gives more consistent throughput, which had been
variable depending on how the application set up the mbuf.
The message builder code had to be considerably re-factored
to do this efficiently.

Cleanup of unused code.
Rename and simplify a badly named struct element, was aes, but

This patch changes the qat firmware session data structure from a fixed
size to a variable size which is dependent on the size of the chosen
algorithm.
This reduces the amount of bytes which are transferred across
PCIe and thus helps to increase qat performance when the
accelerator is bound by PCIe.

This patch adds a PMD for the Intel Quick Assist Technology DH895xxC
hardware accelerator.
This patch depends on a QAT PF driver for device initialization. See
the file docs/guides/cryptodevs/qat.rst for configuration details
This patch supports a limited subset of QAT device functionality,
currently supporting chaining of cipher and hash operations for the
following algorithmsd:
Cipher algorithms:
- RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)
Hash algorithms:
- RTE_CRYPTO_AUTH_SHA1_HMAC
- RTE_CRYPTO_AUTH_SHA256_HMAC
- RTE_CRYPTO_AUTH_SHA512_HMAC
- RTE_CRYPTO_AUTH_AES_XCBC_MAC
Some limitation on this patchset which shall be contributed in a
subsequent release:
- Chained mbufs are not supported.
- Hash only is not supported.
- Cipher only is not supported.
- Only in-place is currently supported (destination address is
the same as source address).
- Only supports session-oriented API implementation (session-less
APIs are not supported).
